Conditions: temp:0.00; pressure:0.00; stir:

Conditions: temp:80.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To the solution of N-methyl-4-(2-(methylsulfinyl)benzo[d]thiazol-6-yloxy)picolinamide (25 mg, 0.072 mmol, 1.0 eq) in 1 mL of IPA and 1 mL conc. HCl was added 2-(2-(4-methylpiperazin-1-yl)ethoxy) aniline (25 mg, 0.108 mmol, 1.5 eq) and reaction mixture heated at 80° C. in oil bath for 2 hours. Thereafter, the product was purified via reverse phase HPLC. This procedure was generalized for other analogues for which progress of the reaction was monitored by LC-MS and amount of aniline and reaction time adjusted as needed. LC/MS (m/z) [519.1] (MH+) Thereafter, the product was purified via reverse phase HPLC was monitored by LC-MS and amount of aniline and reaction time
